Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(1,2)(3,4)(5,6,9,12,8,11,10,7)(13,14,17,20,16,19,22,25)(15,21,24,28,23,18,26,27);(2,4)(5,7,9,6,8,12,10,11)(13,15,22,26,16,23,17,24)(14,18,25,28,19,21,20,27);(6,7)(9,10)(11,12)(13,14)(15,18)(16,19)(17,25)(20,22)(21,23)(24,28)(26,27);(2,4)(6,11)(7,12)(14,19)(15,23)(20,25)(24,26)
